Saharan dust plume . . . and mechanism to spread orchids? Male
Default Saharan dust plume . . . and mechanism to spread orchids?

I saw on the Weather Channel website that there is an enormous cloud of wind-borne dust that has crossed the Atlantic, east-to-west, in the Caribbean now, expected in Texas this weekend.

Yes, I know the Sahara is not a place for orchids, but I do wonder if winds are also moving through less arid parts of Africa, and possibly carrying that dust along and into this massive dust plume? Potentially bearing dust-like orchid seeds too?

Might explain how at least some orchids have moved, from one land mass to another, over time. No doubt some also ended up on different land masses that drifted apart with plate tectonics in prehistory.

Just food for thought.

Sure, why not?

Think volcanic islands, they are sterile. Wind and animals are what spread seeds.
